Phase Shifting with DSP using the Teensy

In this video I do some DSP Phase shift processing with the Teensy 4.0. Some other DSP videos I have:
STM32 DSP: • DSP with Nucleo 144 F7...
ESP32 DSP: • ESP32 IoT Radio - Part...
Big shout out to Charlie Morris' channel for all the inspiration. Lots of great stuff on his channel

Correction: I meant to say "I2S" not I2C
Here's the Iowa Hills software site

I am using the Hilbert Filter from this page

Note I missed out a critical parameter in the Hilbert filter configuration and that is you have to put in the desired phase offset in the "Phase Add" field (i.e. +45 and -45)
Here's some DSP theory pages. The convolution algorithm
